Which of the following is NOT one of the rapid plotting techniques?

• A. Line
• B. Box
• C. Column
• D. Triangle

Answer: (D)

Rapid plotting techniques are quick-symbol methods used on plotting boards to convey status at a glance during damage control. Line plotting is used to show trends or progression and is fast to sketch and read as a continuous change. Box plotting provides clear, bounded groups to represent related data or discrete statuses in a compact form, easy to draw and interpret. Column plotting uses vertical bars to indicate values across categories, making comparisons immediate and straightforward. A triangle, while a valid shape in some charts, isn’t a standard rapid plotting tool in this context because it doesn’t map as cleanly to quick, universally understood status indicators; its meaning can be ambiguous and orientation-dependent, which slows interpretation under stress. So the triangle isn’t considered a rapid plotting technique.
